Purpose. This study reported on body type perception of people aged ${\geq}19years$, regardless of gender, and on its association with disease morbidity and the quality of life and aimed to observe the effects of stress on body weight perception, disease morbidity, and the quality of life. Methods. The data from 218,899 persons aged ${\geq}19years$ who were respondents to the 2010 Community Health Survey were finally analyzed. A designated program was used to perform complex sample analysis; chi-square test was carried out to determine body type perception by the general characteristics and disease status and analyze health-related behavior and weight control behavior by body type perception, and multiple logistic regression was used to observe the effects of body type perception on mental health and the quality of life. Results. 34.9% of all the respondents misperceived their body type and females were more likely to misperceive their body type. The older they were, the more poorly they perceived their body type; those perceiving their body type poorly were significantly more susceptible to both hypertension and diabetes. When correction was made in relation to gender, age, and so on, those perceiving their body type excessively were more susceptible to hypertension (1.43[1.367-1.050]) and diabetes morbidity (1.36[1.294-1.428]). Body type perception affected the quality of life: the respondents perceiving their body type poorly (0.91[0.884-0.940]) or excessively (0.75[0.720-0.770]) showed lower quality of life than those perceiving their body type correctly. Conclusions. Distorted body type perception affected disease morbidity and the quality of life: the respondents excessively perceiving their body type were significantly more susceptible to both hypertension and diabetes and those perceiving their body type excessively or poorly showed lower quality of life than those perceiving it correctly. It is therefore necessary to make multilateral efforts to cultivate correct body type perception.

This paper takes another approach in assessing students' perception of mathematics. Instead of asking for verbal description of the students' perception of mathematics, we asked the respondents who were all college students to draw their perception of mathematics. This relatively new approach enabled students to take a second look of how they perceived math and, at the same time, explored students' creativity and provided a less austere appearance to mathematics which was taken usually in a more formal and severe manner. This approach of assessing students' perception of mathematics generated new information that could not be normally gleaned from other approaches like Likert Scale. Some drawings of mathematics of the respondents reinforced their math affect towards mathematics. For those who hated math, their drawings revealed so the same is true with those who loved mathematics. Examining the visual representations of mathematics and looking for commonalities, the researcher found a number of interesting themes that may shed some light to educators' understanding of students' math affect.

This study was attempted to investigate the main factors affecting health perception of the patients following cardiac valve replacement surgery. Data were collected from Sept. 1 to Oct. 31, 1984 through administration of questionnaire developed for this study by the researcher. The subject was 95 patients who received follow up care following cardiac valve replacemert surgery at S.N.U.H. The data were analyzed by T-test, oneway ANOVA, pearson correlation and multiple regression according to dependent variables. The results were as follows. \circled1 Average self-health perception of those patients. were 4.62, (maximum; 7 minimum; 1) and they showed on affirmative response for their health condition, \circled2 There was significant difference in health perception according to sex difference. Men had higher health perception than women. (t=2,83, p=0.006) \circled3 There was significant difference in health perception according to occupation. Those who had occupation showed higher health perception those who had no occupation. (t=3.25, p=0.002) \circled4 The longer post-operative period elapsed, the higher health perception was, and there was significant difference in health perception (f=0.2958, p=0.002). \circled5 The higher age was, the lower health perception was, and there was a significant difference in health perception. (${\gamma}$= -0.2485, p=0.008) \circled6 The fewer subjective psychosomatic symptoms were, the higher health perception was, and there was a significant difference in health perception. (f = -0.4988, p=0.0000) \circled7 The more active daily activities were, the higher health perception was, and there was a significant difference in health perception. (${\gamma}$=0.6359 p=0.0000) \circled8 The main factors predicting health perception .are like these. \circled1 Daily activities (42.7%), highest variable. \circled2 Psychosomatic symptoms (7.29%) \circled3 Elapsed period after cardiac valve replacement surgery (1.89%) \circled4 Existence of occupation (1.87%) \circled5 Sex (1.78%) \circled6 Age (0.8%).

이 연구의 목적은 고등학생들의 2015 개정 과학과 교육과정 진로선택 교과목인 '과학사' 과목과 과학과 역사의 관계에 대한 인식을 탐색하는 것이다. 또한 이 연구는 실제 과학사 수업을 경험하기 이전과 이후의 이 인식의 변화를 계열별로 비교하였다. 이를 위하여 고등학생 265명이 그린 과학사와 과학, 역사와의 관계를 표현한 벤다이어그램 도형 자료를 수집하고, 이에 대한 설명 텍스트를 수집하였다. 수집된 자료들은 귀납적으로 범주화하여 최종적으로 범주화하였다. 벤다이어그램 자료를 분석한 결과 '과학과 역사의 만남으로서의 과학사', '독립영역으로서의 과학사', '역사의 일부로서의 과학사', '과학의 일부로서의 과학사', '모두를 아우르는 과학사'의 5가지의 다양한 관계범주 유형을 발견할 수 있었다. 또한 각 유형들마다 다양한 세부유형들이 존재함을 확인할 수 있었다. 또한 과학사 수업 경험 이전에는 많은 학생들이 과학사를 과학 과목과 역사 과목의 교집합으로 여기는 경향을 보였다. 그러나 과목 경험 후에는 인문계 학생들과 자연계 학생들의 관계인식변화는 서로 달라졌다. 인문계 학생들의 경우에는 과학사 과목이 역사과목의 일종이라고 여기는 인식이 더 증가했고, 자연계 학생들의 경우는 과학의 일종이라고 여기는 인식이 더 증가했다. 이와 같은 연구 결과를 토대로 과학사 교육이 기존에 자신이 속한 계열 내에서 익숙하게 배우는 기존의 교과들과는 다른 새로운 관점을 경험할 수 있는 과학사 교수-학습이 실현되어야 할 것임을 제언하였다.

The present research examined the contribution of sounds′ familiarity to auditory distance perception, while attempting to control the influences of unavoidable physical characteristics among sounds. Different vocal "styles" ("shouts", "whispers" and "a normal conversation") of man and woman were recorded digitally and presented from a stationary loudspeaker to blindfolded listeners in a semi anechoic chamber. Playback levels were adjusted to remove extraneous sound level cues. The results showed that the shouting voice was judged as appearing farthest, the whispering voice closest, and the conversational voice was intermediate. The findings suggested that the perception of auditory distance may be affected by past experience (or familiarity).

Due to Thailand's nuclear energy public acceptance problem, the understanding of nuclear energy public perception was the key factor affecting to re-consideration of the nuclear energy program. Thailand Institute of Nuclear Technology and its alliances together developed the classification model for the nuclear energy public perception from the big data comments on social media using Facebook using deep transfer learning. The objective was to insight into the Thailand nuclear energy public perception on Facebook social media platform using sentiment analysis. The supervised learning was used to generate up-to-date classification model with more than 80% accuracy to classify the public perception on nuclear power plant news on Facebook from 2009 to 2022. The majority of neutral sentiments (80%) represented the opportunity for Thailand to convince people to receive a better nuclear perception. Negative sentiments (14%) showed support for other alternative energies due to nuclear accident concerns while positive sentiments (6%) expressed support for innovative nuclear technologies.
